Notes proper interaction and communication. Especially in a situation where the participant are far away
from each other, their interaction is not possible or dissipation of more time, money and power matters
in such meetings, then it is better to use teleconferencing rather than formal conferencing and mutual

communication. In this way, teleconferencing or distance communication system can be defined as a
communication system in which two or more people sitting at distant place can communicate through
some electronic medium in the similar manner as they are communicating with each other by sitting in
front of each other.

Fig.—Teleconferencing Instrument
“In a teleconference, aimed at total interaction, all three types of media are integrated to supplement
one another. A state of the art teleconferencing facility would have multi-directional video and audio
transmission systems as well as some other means such as document transmittal, electronic chalkboard
and videotext.”
More than one telephone lines are required for teleconferencing along with mutually related techniques.
It is called communication method. Adding devices to each communication is considered as normal
practice. Handsets, top sets, speaker phone, radio and telephone etc. are necessary for communication.

What is teleconferencing?

In fact, teleconferencing or teleconference is a real-time interaction between two or more people.
Teleconferencing is that electronic system, in which two or more people at distant locations can
participate in the discussion of their desired topics, can express his ideas, can listen to others, and can
provide immediate feedback, suggestions and comments on them along with exchange of required
information.
“Teleconferencing offers a means of interacting with others at remote places by circumventing travel
costs, time and associated problems. Educational applications pertain to communication with group of
learners at different campuses and in different organisations. Further application includes information
sharing and consultation.”
In this way, it is possible to utilize developed electronic components in the form of teleconferencing
such that people sitting thousands or millions kilometres away can remain engaged in dialogue and
conversation in the same way that they are interacting with each other, sitting under a roof of a hall
conference hall. As far as the question of the historical origin of this type of system, this trend began via
U.S. telephone (TEL) and telephone picture phone in 1960.
